Yu Kuai 06257fda83 blk-wbt: cleanup rwb_enabled() and wbt_disabled()
'wb_normal' will set to 0 if 'min_lat_nsec' is 0, and 'min_lat_nsec' can
only be set to 0 through sysfs configuration where 'WBT_STATE_OFF_MANUAL'
is set together, in the meantime, they can only be cleared together
through sysfs afterwards. Hence 'wb_normal != 0' is the same as
'rwb->enable_state != WBT_STATE_OFF_MANUAL'.

The code is redundan, hence replace the checking of 'wb_normal' to
'enable_state' in rwb_enabled() and reuse rwb_enabled() for
wbt_disabled().
